| 11. | Chlorine is very rare in lunar regolith, so the design recycled it.
|
| 12. | Ida's regolith is composed of the silicate minerals olivine and pyroxene.
|
| 13. | Its small size would make the formation of significant amounts of regolith impossible.
|
| 14. | Regolith can vary from being essentially absent to hundreds of metres in thickness.
|
| 15. | In less arid regions, however, the regolith profile can vary considerably.
|
| 16. | Analysis of the plume observations supports the presence of water in the regolith.
|
| 17. | They also took some rake samples, netting 78 fragments from the regolith.
|
| 18. | The limiting element was Chlorine, an essential element to process regolith for Aluminium.
|
| 19. | This contrasts with Ida, which is covered by a deep layer of regolith.
|
| 20. | Regolith is also important to engineers constructing buildings, roads and other civil works.
